Specification of Letters Patent.

Patented Aug. 9, 1910.

Application :filed November 18, 1909. Serial No. 528,764.

To all whom it may concern: y

Be it known that we, JAMES R. MGWANE and WILLIAM D. Moolen, citizens of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented a new and useful Portable CoresS upport, of which the following is a specification.

The invention relates to a portable core support.

The object of the present invention is to provide a support, adapted to hold a plurality of cores in position for enabling the same to be simultaneously lifted and transferred from the support to a multiple flask, and inserted therein by a crane without permitting the cores to strike against each other.

Another object of the invention is to pro-` vide a portable core support, adapted to enable a plurality of cores to be quickly and conveniently carried to a pipe pit from a core car, or other means for making and drying cores, whereby the cores may be prepared any distance from a pipe pit without inconvenience in handling them or danger of injuring them in transferring the cores to the pipe pit or other point where the said cores are introduced into the flasks.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims may be resorted to without departing from the spiritor sacrificing any of the advantages of the invention.

In the drawings ,Figure l is a side elevation of a portable core bar support, constructedin accordance with this invention. Fig. 2 is an enlarged plan view of the same, the draft rod being broken away and the core bar being illustrated in dotted lines. Fig. 3 is an elevation of the rear end of the portable core bar support. Fig. 4 is a similar view of the front end thereof. Fig. 5 is a perspective view of the inner and outer core bar receiving brackets or stands of the front truck.

Where the words core bar are used they are intended to cover the idea of core and bar, the core having been swept up on the bar and dried.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the embodiment of the invention illustrated in the accompanying drawings, the brackets or stands l, 2, 3 and a for the core bars 5 and 6 are mounted upon a car in order to enable the core bars to be quickly and conveniently transferred from a core strike, or other means for making and preparing core bars, to the pipe pit, or other point where the core bars are introduced into the iiasksfbut the brackets or stands may be mounted `in a fixed position adjacent to a pipe pit or other convenient place, and the core bars may be placed on the said brackets or stands by hand. The car is composed of trucks 7 and S, equipped with wheels 9 and connected by a draft rod l0, fixed to the frame of thetruck 7, and slidable through the frame of the truck 8. The trucks may be of any` preferred construction, and the draft rod 1()\.preferably pierces the frame of the front truck 7 and is threaded at ll and l2 in advance and in rear of the same for the reception of nuts 13 and la, arranged in pairs and adapted to rigidly secure the front end of the rod 10 to the frame of the front truck. The frame of the rear truck 8 is provided with a central opening' through which the rear portion of the draft rod passes, and the rear terminal 15 thereof is threaded for the reception of nuts 1G, forming a stop for retaining the draft rod and the truck in their slidable relation. The rear truck may be equipped with suitable anti-friction devices to enable the same to slide freely on the draft rod, but this is not essential, and as such devices do not constitute a portion of the pres ent invention, illustration thereof is deemed unnecessary. The truck 7 in the present description is termed the front truck for convenience, as the brackets or stands for the upper or shackle ends of the core bars may be mounted in either truck.

The brackets `or stands shown in the accompanying drawings are designed to hold a set of core bars for use in a four-way or multiple flask, and the core bars G are arranged at a higher elevation than the core bars 5, as clearly illustrated in Fig. l of the drawings, and each core bar is located in a different vertical4 plane, as shown in Fig. 3 of the drawings, the core bars being staggered both laterally and vertically in order to prevent them from striking against each other vadjacent lower core bar 5.

and being injured when they are lifted from. the car by a crane. The front brackets or stands 1 andV 2 receive the shackle ends of the core bars 5 and (3, and the rear brackets or stands 3 and 4, which support the other ends of the core bars, receive wooden sticks or bars 17, which are inserted in the core bars to facilitate carrying thesame.

Each of the brackets or stands is preferably constructed of a single bar or piece of metal bent into the form shown. The front bracket or stand 1 is provided with curved seats 18 and 19, arranged in the same horizontal plane and spaced apart a sufficient distance to permit one of the upper corey bars G to lie above the intervening space between'the said lower co-re bars The ad jacent sides of the curved seat-s 1S and 19 are extended upward to the top of the bracket or stand: and are connected by an angularly bent approximately L-shaped horizontal portion 20, the seat 19 being located slightly in ad vance of the seat 18. The outer side of the seat 18 is also extended tothe top of the bracket' or stand, and is connected by a straight transverse portion 21 with the adj acent side 22 of the bracket or stand. rllhe side 22 of the bracket or stand is vertical, and has its lower endy bent outwardly and bolted or otherwise secured to the frame of the truck, The seat 18 is formed by an approximately U-shaped loop or portion of the bracket or stand 1, andthe seat 19 is formed by an approximately J-shaped portion, which is connected at the outer terminal with the adjacent side 23 of the bracket or stand 1. This leaves the bracket or stand 1 open at the outer side of the seat 19, and the side 23 of the bracket or stand is short, and has its lower terminal extended inwardly and bolted or otherwise secured to the frame of the truck.

The inner front bracket or stand 2 is provided with curved seats 24 and 25, located at the top of the bracket or stand in the samel horizontal plane. The seat 25 is located in advance of the seat 24, and .is connected by a short horizontally disposed longitudinal portion 26 with an approximately U-shaped portion 27, spacing the seats 24 and 25- and providing an open space located opposite the seat 18 for the passa-ge of the The seat 24 is connected directly at its outer end with the vertical side V28of the bracket or stand 2. This'si'de 28 of the bracket or stand is relatively long and the other side 29 is relatively short, being connected with the seat 25'by a curved approximately J-shaped portion 30, which forms an opening opposite the-seat 19. The sides 28 and 29 of the bracket or stand 2 have their lower terminalsextended in opposite directions and of the seat 24 and by locating the seats of the front brackets or stands in. different transverse planes, the shackles are also located in different longitudinal planes, and are in proper position to be readily engaged with the hooks 31 and 32 of a core bar carrier 33, as clearly shown in Fig. 1 of the drawings.

The inner rear bracket or stand 3 is provided with curved seats 34 and 35, located inthe same horizontal planes and connected with each other by an intermediate angularly bent portion 36. The seats 34 and 35 are connected with sides 37 and 3S of the bracket or stand, which have their lower terminals extended in opposite directions and secured to the frame of the rear truck. The outer rear bracket or stand 4 is of substantially the same construction as the inner rear bracket or stand 3 with the exception of the seats 39 and 40, which are curved and located in different longitudinal planes than the seats 34 and 35 and at a higher elevation, the sides 41 and 42 being extended above the horizontal plane of the top of the bracket or stand 3, as clearly illustrated in Fig. 3 of the drawings.

Then the core bars are placed in the seats of the front and rear brackets or stands, they are arranged at different elevations, two of them being located above the other two. The members of the pair of upper core bars are arranged in the same approximately horizontal plane, the upper core bars 6 of being slightly inclined, as shown in F ig. 1, and the members of the pair of lower core bars are arranged in the same horizontal plane. Ailso each core bar is located in a different transverse and a dilterent vertical plane from the other core bar.

The hooks 31 of the core bar carrier 33 are of a length greater than the hooks 32. rlhe hooks 31 and 32 are connected with chains 43, which are spread by arms ot a spider 44, to maintain the hooks in proper position with relation to the compartments of the four-way flask, in which the core bars are to be introduced. The chains 43 are connected with a central chain 45, which is suitably connected with the chain of the crane (not shown), and when the core bar carrier is raised, the shackle ends of the core bars are lifted from the brackets or stands of the front truck, and the gradual raising of the front ends draws the rear ends of the core bars forwardly beneath the core bar carrier, the rear truck being moved forwardly along the draft rod, so that the, core bars do not leave the rear brackets or stands until they are in approximately a vertical position. This enables the core bars to be simultaneously liftedI from the support by a crane without injuring each other. lVhen bolted or otherwise secured to the' frame of the core bars are suspended from the carrier,

the truck. The seat 25 is located in advance they hang in proper position to enable them llO to be inserted in the compartments of a fourway flask. The compartments of a fourway flask are arranged so close to each other that it is impossible to arrange the core bars on the brackets or stands in a position corresponding strictly to the relative arrangement of the said compartments, and it is necessary to stagger the core bars on the support in order to prevent them from striking each other when they are lifted from the support by a carrier having its supporting means arranged to suspend the core bars in proper position for inserting the same in the compartments of a flask. Although four core bars are shown in the accompanying drawings, yet the brackets or stands may be arranged to accommodate a different number of core bars.

Having thus fully described ourinvention, what we claim as new and desire to secure by Letters Patent, is
